Storage spaces are formed between adjacent pairs of girders by bringing the connected girders together into side-by-side relationship. Each portion of the flexible sheet between adjacent pairs of girders is stored in the storage space formed between the respective pair of adjacent girders. Heat insulating material is placed on the portions of the flexible sheet between adjacent, moved apart pairs of girders.
